Determining speech rate from audio
I am looking for a way (e.g. an app) that can determine how fast someone is speaking, in realtime. This kind of biofeedback would be really useful for many people with communication disorders where learning to speak slower can help a lot (e.g. stuttering, dysarthria). I can also see it being useful for teaching public speaking to students etc.
Does anyone know of anything out there (hardware or app) that can do this? Or where I might find someone I could pay to develop this app?
